Artiklen udfolder det syn på forholdet mellem religionsvidenskab og religionsundervisning, som har præget Hans Jørgen Lundager Jensens virke som underviser, formidler og studieleder. For Hans Jørgen viser religionsvidenskabens samfundsrelevans sig i uddannelsen af gymnasielærere, der kan formidle et bredt kendskab til religion til unge mennesker og vise dem, at religion ikke er så tosset endda. Hans Jørgens syn på religionsvidenskabsstudiet som en gymnasielæreruddannelse blev formet i hans egen studietid på kristendomskundskab i 1970erne, men det er lige så aktuelt i dag som dengang. Hans ideer har inspireret nærværende artikels forfatter i arbejdet med et styrke religionsundervisningen i Holland. ; The article discusses Hans Jørgen Lundager Jensen’s view of the relationship between the study of religion as an academic discipline and religious education in Danish high schools. For Hans Jørgen, the societal relevance of our discipline lies in the education of high school teachers who can communicate solid knowledge of the world’s religions and challenge stereotypes and prejudices. Hans Jørgen’s ideas on the study of religion as academic teacher training were formed during his own studies in the 1970s of what was then called the Study of Christianity (kristendomskundskab), but they are equally relevant today. His views have inspired the author of the present article in his work on improving religious education in the Netherlands.
